“…Therefore, an analysis of the influence of urban planning features in the seismic performance of the structures is necessary in order to obtain an adjusted approach of the damage scenarios. In both cases, in spite of the damage distribution not being homogeneous, the modeled results reflect that the most vulnerable areas to a certain seismic action were mainly concentrated in the northeast neighborhoods and the central and southwestern areas of the city, as has been presented in some studies [27,40]. Precisely, these zones suffered widespread damages in buildings after the 11 May 2011 earthquake, even with the collapse of one entirely residential building [5,6].…”

“…Furthermore, since in reality the majority of the buildings in urban areas, especially those located on low-to-moderate seismicity territories, have no seismic structural joint between buildings (or such a joint is not wide enough or has not been executed correctly), cracks in masonry infill walls and even in structural elements can frequently be detected in the joint between contiguous constructions [27,34]. Consequently, a penalty value of 0.04 has been conservatively reflected, excluding those buildings executed with high level seismic regulations.…”

“…Taking into account different experiences after post-earthquake evaluations [16,26,27], these standards are defined in a ±0.02 range for an interval between −0.08 and +0.08 in order to incorporate them into the characterization of the seismic vulnerability. Since the previous described version [18] a series of reviews have been performed in the definition and numerical evaluation of these behavior modifiers [23,25,28,29], calibrating the influence of several dispositions (i.e., sloping ground difference of height between close buildings, irregularity in plant or elevation, etc.…”

Featured Application: Geographic Information System (GIS) estimation of ante-earthquake scenarios through a more functional and standardized method of seismic vulnerability evaluation of reinforced concrete buildings in urban areas. Abstract:In spite of the enhancements related to building construction, many regions still present a major level of seismic risk as a consequence of the high vulnerability of the urban configuration of their cities. An improved method to assess the seismic vulnerability of buildings in urban areas is proposed in this contribution in order to advance the management of seismic emergency scenarios. The methodology, mainly based on the cadastral database, allows for a more standardized implementation as a function on the typological, structural, and urban parameters of the buildings, reducing the level of uncertainties linked to these methodologies and giving continuity to the different RISK-UE published works. The generalization of the method to any urban area has also been improved by means of removing the parameters whose calibration is associated with a specific area. The methodology has been put into practice in the urban area of the city of Lorca (SE Spain), in the aftermath of the earthquake of 11 May 2011, due to the availability of well-documented data reported from this seismic event. The proposal, when it is combined with Geographic Information System (GIS) techniques, provides valuable information for the planning and management of post-earthquake emergency situations.

We present a procedure for exposure and vulnerability evaluation that integrates LiDAR, orthophotos, and other ancillary datasets. It comprises three phases: (1) city stratification into homogeneous regions; (2) exposure database compilation; and (3) vulnerability allocation using predictive modelling. We have conducted two applications in Lorca (Spain) and Port-au-Price (Haiti) and here we compare them. Each phase of the method is subject to variations due mainly to data availability; however, it does not affect the final accuracy that remains high in both scenarios (over 80%). It is a flexible procedure that is able to adapt to the particular features of two different cities.

“…The main objective was to recognize the city and capture physical information in the survey at two scales: census tract and urban parcel. The study area, the center of Valdivia, was selected according to its constructive heterogeneity where data related to urban modifiers [3] were taken, which will serve as a basis for the calculation of vulnerability indexes.…”

The present work is part of the resilience study of urban areas, where the study area is the urban center of Valdivia (Chile). The aim is to catalog and identify buildings and urban blocks for the subsequent evaluation of exposure and vulnerability to seismic risk. This is done through a collaborative mapping with the participation of a local team of volunteers (of the Technological University of Chile INACAP) that was previously trained on vulnerability issues and OpenStreetMap platform. The study area comprises 83 urban blocks. Each urban block is subdivided into parcels, which contain buildings with different type of construction and different uses. In the future, this research will continue with the development of urban resilience indexes at physical and social scales.
